IMPROV EMENT IN CARPENTERS GAGES.

Specification forming part of Letters Patent No. 1 50,732, dated May 1'2, 1874; application filed March 5, 1874.

- understood from the specification and drawing.

Figure l is a side view. Fig. 2 is a top view.

Fig. 3 is an end view of the stock out through the line 1. Fig. 4 is a lateral section of the stock out in the direction shown by line 2, showing the gage-tooth, and how it is held firmly, tightened, or loosened by a screw, 0;

.Fig. 5, gage-head'and clamp.

a is-a T-shaped gage-bar or stock, having a groove, 1), to receive a gage-tooth slide-bar, c,

flush, or nearly so, with the curved finished surface d, having a gage-tooth, e, secured by turning the head of screw 6 against the body of the tooth, and a scale marked 011 its surface to aid in settingthe gage-head in the common way. f is the gage-head, having a depression or groove of the proper depth and width, with a convex bottom to fit closely and work freely upon the face at of the stock a. The face of the gage-head. f is formed so as to work at right angles with the stock. 9 is a grapplin g-clamp, provided with a thumb-screw,

h. This clamp is placed over the gage-head in the notches '5. Then the head, with the grappling-clamp, is placed on the bar from one end. The prongs 70 take bearing on the under side of the bar-plate, when the gage will be complete and ready for use as a mortise-gage; or, by removing the head, the gage slide-bar 0 may be turned over, the other edge up, the thumbpiece m placed into the orifice n. Thus the upper edge will be nearly flush with the face of the gage-bar, to be used as a common gage. By loosening the screw 0 the tooth (2 may be removed, replaced, adjusted, and again firmly secured in the desired position by turning up the screw 6, and the head f adjusted and secured in its desired position by the screw it and clamp g. Thus I am enabled to produce a good, cheap, and durable gage.

I am aware of Patent N 0. 141,014, bearing date July 22, 1873, and hereby disclaim anything shown therein.

What I claim, and desire to secure by Letters Patent, isv The combination of the T-shaped bar a, grooved head f, grappling-clamp g, and slide gage-bar c, substantially as and for the purpose set forth.
